G'qRB- GUARD AND ANCI-IORING AND POSITIONING DEVICE THEREFOR.

Specification of Letters Patent.

Patented July 25, 1916.

Application filed October 1, 1914. Serial No. 864,382.

To all whom it may concern Be it known that I, AN'rHoNY ELTON DAVIS, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Curb-Guard and Anchoring and Positioning Device Therefor, of which the following is a specification.

In my prior Patent No. 1,105,260, granted to me July 28th, 1914, I have described and claimed ametal bound curbing which may be advantageously employed toprevent the breaking or shaling olf of the concrete due to the impact or abrasion of the wheels of vehicles to which the curb is exposed in use.

In accordance with my present invention, I have devised a novel curb guard and anchoring and positioning means therefor, which accomplishes improved results, and the corner of the curb is reinforced by means of a novel bar which interlocks in a novel manner with respect to the anchoring and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein set forth.

Figure 1 represents a perspective view of a curb guard and positioning and anchoring device therefor, in assembled position. Fig. 2 represents a sectional elevation of Fig. 1. Fig. 3 represents a section on line m:'c of Fig. 2. Fig. 4 represents a sectional elevation of another embodiment of my invention. Fig. 5 represents a perspective view of the curb guard, in detached position.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :-1 designates a curb guard within the scope of my invention, and it is illustrated as consisting of a T-shaped bar having a longitudinally extending web 2 connected to the head of the bar, the outer face of such head being rounded as at 3, and provided with sub stantially flat faces 4 and 5. The bar is formed in such a manner that shoulders 6 and 7 are formed, which may be directed at any desired angle with respect to the faces 4 and 5. The inner face of the head of the T-bar is provided with the faces 8 and 9 respectively, which extend outwardly substantially at right angles to the web 2. The web 2 is provided at intervals with apertures 10 therethrough and also with preferably larger apertures 11 located at opposite sides of an aperture 10.

12 designates an anchoring and positioning device which consists of a body portion consisting preferably of sheet metal and provided with a top face 13, which terminates at its inner end in a flaring or wedgeshaped face 14, which'extends to the inner wall 15, which latter is preferably substantially vertical. The bottom face 16 is preferably substantially parallel with the top face 13, and the front face 17 is preferably at right angles to the bottom face 16. The front face 17 is provided with an inwardly extending recessv 18 and with an angularshaped recess19.

2O designates an upwardly extending portion of the anchoring device 12.

21 designates a lug, which is formed by the angularly inclined slot 22, said lug be ing directed rearwardly and having its top face rounded as at 23.

By the above construction, faces 24 and 25 are formed on which the web of the T- bar is seated. The body portion of the anchoring device is provided with a series of elongated apertures 26, 27 and 28 respectively, which are filled with the binding material such as cement or concrete 29 when the construction is completed. In some cases, it is advantageous to employ a cotter or other pin 30, which passes throughan aperture in the lug 21 in order to interlock the curb guard with its respective anchoring device. I

In the embodiment seen in Fig. 4, instead of aperturing the lug 21' as seen in Figs. 1 and 2, I provide an enlarged aperture 31, which extends on opposite sides of the web 2 when the parts are assembled so that when the concrete is poured in, it will flow through and surround the portion of the web 2, which passes through the aperture 31 and firmly in jeo terlock the curb guard to its anchoring and alining elements. I

It will be apparent that, in the embodiment seen in Figs. 1 to 3 inclusive, it is within the scope of my invention to omit the pins 30 and also the apertures therefor. If the apertures are present and no pins employed, the concrete will flow through and fill such apertures and thereby interlock the web of the curb guard to its respective anchoring elements.

In laying the curbing, the bar 1 and the anchoring devices 12 may be interlocked with each other prior to the placing of the curb guard in the mold or subsequently thereto. The anchoring devices 12 may be first positioned in the molds and the T-bars assembled with respect thereto by bringing the apertures 10 into register with the lugs 21, whereupon the T-bar may be lowered and assume the positions seen in Figs. 1 and 2 respectively, it being seen that the web of the T-bar will be seated on the faces 24: and 25 of the anchoring device and the face 9 of the head of the T-bar will be seated on the outer face of the lug 20, so that the face 5 of the head of the curb guard is in alinement with the front face 17 of the anchoring device. The concrete or other binding material employed is then poured in and fills the apertures or pockets 26, 27 and 28, the slot 22 and the recesses formed by the faces 18 and 19. Owing to such apertures and recess and the contour of the anchoring devices, the concrete will interlock therewith in such a manner as to position and secure the curb guard in alinement with the rise and tread of the curb and reinforce the construction in the manner desired.

By the employment of my present invention, the parts may be economically constructed since the T-bar may be formed by a rolling operation and the anchoring devices may be readily cast or stamped. The anchoring devices may be readily assembled at proper intervals with the web of the curb guard before placing the guard in the mold or after the curb guardhas been placed in the mold, and the anchoring devices will position the curb guard so that it will assume the correct position with respect to the top and front wall of the finished construction.

Attention is directed to the fact that the shoulder 7 in the form illustrated is substantially at right angles to the rise ofthe curb, and the shoulder 6 in the form illustrated is at substantially right angles to the tread of the curb. By such construction, the feathering of the concrete, such as occurs when the sides of the head of the bar are rounded, is prevented, and a better joint is obtained between the concrete and the head of the curb guard. The curb guard may be provided with any desired number of apertures 11, which in practice are located at desired intervals along the length of the web so that the concrete will flow through and fill such apertures and an additional interlocking of the curb guard with respect to the concrete is obtained.

In so far as I am aware, I am the first in the art to devise a curb guard wherein the anchoring devices are positioned in the mold and the bar can be assembled with respect thereto by simply lowering it to place on the anchoring devices, the bar being positively anchored in the concrete by such devices, and my claims to such features are to be interpreted with corresponding scope.

It will now be apparent that I have devised a novel and useful construction of a curb guard and anchoring and positioning devices therefor, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will be found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A device of the character stated, comprising anchoring devices having upwardly extending lugs at their forward ends and inclined walls adjacent to said lugs and a bar having a web with apertures therein, whereby when the anchoring devices are positioned and the apertures in the web register with said lugs said bar may be lowered onto said anchoring devices to seat on the inclined walls thereof, said lugs passing through the apertures of said bar.

2.
